The primary object of the invention isto,

provide such a cup in a form which shall be very simple and cheg'p atthe Sametime' sha and durable. i

Another object is to provide a very neat.. and eflicient knurling forthe cap of the cup.v To the above ends, the invention consists 'of thecombinations of arts hereinafter described and summarize in the claims.

' In the drawings, Figures 1 and 2 are vertical diametric sectionsthrough the grease .cup in planes at right angles to each other; Fig. 3is a horizontal section through the cup; Fig. 4 is a vertical sectionthrough a cap having a somewhat modified means for holding the detentspring; Fig. 5 is an elevation of such modified holder in a plane at yright angles to Fig. -4.

Briefly stated, 10 in the drawings repre'- lsents the stationary body orcup proper; 2O

Referring more specically to the parts shown, the cup 10 has an internalbore 11 below which is a reduced bore 12. Outside of this reduced boreare external threads 13 by which the cup may be secured into -a`suitable receiving thread. Near its upper end the outer wall of the cuphas an enlargement 14 on which are external threads. The

bore 11. has preferably a cylindrical wall, 'and in this wall, parallelwith the axis, are

formed rooves 15, such grooves being' arranged iametrically in one ormore' pairs.

in construction, andbe eiiicient in service' mg.- The cap 20 ispreferably a stamped sheet Vmetal member. It has a top portion 21 and a.wall 22' bounded by a cylin er but preferably having located about itssurface, near 'One pair of grooves is'shown in the draw-- the top', ribs.23 parallel'with-its 4axis and f extending ajsufiicient distance fromtop to provide an eiicient finger hold for turning the cap. The outersurfaces of the ribs are vflush with the cylindrical wall. On the in nerface of the caps are threads 24 adapted tovscrew onto the external,threads onthe portion 14 of the cup...

Secured to the head 21 'of the cap vand de` pending the-feinte is a`flattened tubular holder 30 which carries the spring' 40. This holder ispreferabl made of sheet metal plateben't on-itself m11) the formillustrated 1n Fig. 2, or in Figs. 4 and 5. Near its -upper end,portions of this holder pass throughoneor more openings inthe head ofthe cap and the upper 1end of the holder is f up-set or peenedeover, asshown at 32. In the form shown in Figs. '1 and 2, adjacent to the underface of the head of the -oa the holder `is provided with an outward ulgeor bead B3. This head, together with the AHaring upward end of theholder cause it to be secured very rigidly to the cap. In theconstruction of Figs-4 and v5, the' holder 30 is cut'and bent at itsupper end to produce a pair of separated tonguesV 34 which pass throughtwo openings in the cap and are lthen upset.

The spring 40 is preferably of the U-shape shown, having aparallel-sided portion occupying the tubular space 30 andk two flaringend portions 41 with returning ends 42, thereby providing springshoulders, which may occupy the grooves 15 or slide around the smoothwall of the bore 11 in passin one groove to the other. The spring is efectively held in place by copeiating in ward ,projections or dents 34formed by pressing inwardly the two flattened sides of thetubular member30.l y
